With just 215g of weight, The Kask Protone has the lowest drag and the fastest heat dissipation coefficients compared to any other ventilated helmet. Thanks to several ventilation holes and a thick padding material, heat and moisture are dissipated very fast, improving comfort and performance without giving up on safety: the top area is reinforced with an internal plastic sub-structure that increases crash protection.
